Crossings of Second-Order Response Processes Subjected to LMA Loadings

Figure 3

Example 5.1: Observed crossing intensity $N(u)$ in the measured stress-solid line; simulated crossing intensity in $100$ times longer signal than measured ($50$ hours)—solid line with dots; the saddle-point approximation ${\mu }^s(u)$ of $\mathsf{E}[N(u)]$—dashed dotted line.
